我如何使用gdb调试go测试

Question

I have some go tests. I would like to debug with gdb.

But the binaries built by go test are thrown away after running.

So how do I do it?

go 1.6 on windows/64

Answer 1

You use go test -c which will produce the executable file xyz.test. Afterwards you use gdb xyz.test to debug.

Just check go test --help for an explanation of the -c flag:

Compile the test binary to pkg.test but do not run it (where pkg is the last element of the package's import path). The file name can be changed with the -o flag.
